Historically in Ireland, Catholics have desired independence for Ireland, while Protestants, who congregated in Northern Ireland, have wanted to maintain political ties to the United Kingdom.
This is still generally the case, though not without some significant exceptions on both sides. Still, the fact that Catholics may outnumber Protestants in the country by 2021 – 100 years after the country was founded – is remarkable.
According to the last census in 2011, Protestants outnumbered Catholics in Northern Ireland by just three percent. More recent numbers show a Catholic majority in every age group of the population, except for those over 60. Among school-aged children, Catholics outnumber Protestants by a wide margin – 51 percent to 37 percent.
